Decade Resistance Standards

Decade Resistance Standards from 1 μΩ to 10 kΩ

Resistance Guildline Instruments


  • Resistance Ranges include Decades from 1 μΩ to 10 kΩ
  • True RTD Simulation with High Decade Resolution
  • Excellent for milli-Ohm and micro-Ohm Applications and Instruments
  • Accuracy Better than ± 0.01 %
  • Temperature Coefficient Less than 5 ppm/°C!


  • The 9340-4T decade resistance standards series are the most versatile and accurate decade resistance standards. 9340-4T Series is available in models from 3 dials to 7 dials and with an industry leading ultra-low end 1 μΩ Step. This unique 9340-4T Series provides resolution and accuracies never before provided in a decade standard. Decade step values below 1 Ω are arranged in a Kelvin Varley configuration.

9340-4T Series of Precision 4-Wire Decade Resistance Standards

Accuracy of the 9340-4T RTD and Decade Resistance Standards are better than ± 0.01 % from the range of 1 Ω to 100 kΩ Steps. As you go lower, the specifications increase, but there is no other commercially available product that is capable of meeting Guildline’s 9340-4T specifications. For example, the 0.01 Decade at 1 % absolute accuracy equates to only a 100 μΩ total error and is 20 times more accurate than other decade boxes and RTD Simulators whose floor specification alone is 2 mΩ. And forget about specifications or values below 1 mΩ, other manufacturers just cannot provide these ultra-low outputs.
